Abstract: 1,169,784. Electric type selection in typewriters. FUJITSU Ltd. 19 May, 1967 [19 May, 1966], No. 23502/67. Heading G4H. In line printer the line is divided into parts and the printing circuits for each part are enabled successively so that parts of the line are printed in turn. In one form described there are 40 character positions in each part. In the first rotation of the type drum the characters are printed in area 1, Fig. 1, the corresponding group of printing hammers 12A being enabled by closing switch 15A. In the second rotation the second group of printing hammers 12B are enabled by closing switch 15B and in the third rotation the third group of printing hammers 12C are enabled by closing switch 15C. The same hammer-magnet driver circuits 13 are used for the three groups, under the control of a shift-register 14 containing 40 bits. The switches 15A-15C may be thyristors which are fired by inputs at the beginning of the drum rotation and held conducting by currents through corresponding diodes. The magnet driver circuits are transistors and each is connected by three diodes to the three corresponding printing magnets. A coded disc rotating with the type wheel generates a character code for each type position. This is stored in a type code register and compared with each of 40 codes from a computer. The results are entered in the shift-register and agreements cause printing of the corresponding characters in the appropriate places in the first area. This is repeated for each character. After a complete rotation the next area is printed in the same way. After the whole line has been printed, the page is advanced to receive the next line. In another embodiment the computer enters each line of data into a buffer core store from which it is read out in groups of forty characters to cause printing as above. " Flagbits " may be stored in the buffer store along with the data to be printed, which are cancelled when the corresponding character has been printed. When there are no more flagbits in the group of forty positions in the store this is an indication that there are no more characters to be printed and the next group can be printed.

Title: Method for the production of casings for projectiles
IPC: F42B12/22
Filed: 1972-05-18
Abstract: 1503143 Heat-treating projectile casings RHEINMETALL GmbH and STEIGERWALD STRAHLTECHNIK GmbH 18 May 1972 [27 May 1971] 23528/72 Heading C7N [Also in Division F3]  In the production of projectile casings, the casing surface is subjected to a heat treatment using an energy beam to effect changes in the structure of the material and/or the surface shape of the casing in certain places or areas over the surface of the casing to facilitate fragmentation of the casing into fragments of the desired size. The process is preferably carried out using a focused electron beam. When the material in pre-selected zones of the casing is heated above its melting point, followed by rapid cooling by self-quenching, very narrowly limited zones are created with metallurgical properties different from the remainder of the material and with fracturing characteristics ensuring the desired formation of optimum splinters. In preferred embodiments linear structural changes are produced over the casing surface in such a way that regular geometric shapes are obtained e.g. rectangles, squares, hexagons or circles. In particular, structural changes taking a linear course over the casing surface can be formed so as to constitute a cohesive network. The heat treatment usually covers a certain depth range of the casing wall. Changes in the surface shape of the projectile casing are produced by removing material from pre-selected zones. Removal of this type by the production of blind holes of a certain shape and depth may be situated, for example, both in the longitudinal and peripheral directions, in each case following one another in a row and the rows supplementing one another in raster fashion. A notch effect is thus obtained. The invention is described with particular reference to medium-calibre projectiles (20-40 mm.) such as AA shells, with reference also being made to largecalibre ammunition (100-200 mm.) and heavycalibre bombs.

Abstract: 989,221. Supply circuits for electrostatic precipitators; protective arrangements. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. July 6, 1961 [July 7, 1960], No. 23736/60. Heading H2H. The terminals 16, 17 of an electrostatic precipitator are supplied through a transformer 13 whose rectified primary voltage provides the excitation for a transductor 23 which in turn supplies the excitation of winding 21 of a main transductor 18, the output current of transductor 23 being normally determined by the setting of a variable ratio auto-transformer 28. When arcing occurs in the precipitator the voltage of transformer 13 falls and thus the excitation and output of transductor 23 is reduced, to produce a similar effect on transductor 18 and so further reduce the transformer voltage, this cumulative action continuing until the are can no longer maintain itself and extinguishes. Thereafter the residual magnetizing current of the transductor 18 will raise the voltage of transformer 13 to increase the excitation and output of transductor 23 and hence of transductor 18, this cumulative action continuing until the normal operating condition of the precipitator is restored. The circuit may include resistance and other elements to further improve the speed of response of the transductors and compensate for the temperature coefficient effects in their excitation windings. For any given setting of the transformer 28 the transductor 18 will pass a constant current over a range of precipitator working voltages. Typical operating characteristics for the transductors are given and discussed, Figs. 2 and 3 (not shown).

Abstract: 677,208. Mixing appliances. CELANESE CORPORATION OF AMERICA. Sept. 29, 1950 [Oct. 1, 1949], No. 23898/50. Class 86 A mixer comprises a chamber containing intermeshing lobed stirrers, means for forcing material to be mixed into one end of the chamber and means whereby the mixed material is discharged from the other end, the chamber and stirrers being so shaped and spaced as to provide sufficient clearance for the passage of a thin layer only of the material whether between the intermeshing stirrers or between the stirrers and wall of the container. As described, the mixer comprises a feed hopper 11 opening into a passageway 12 extending through a casing 13. The passageway 12 has the form of two intersecting cylinders or near cylinders through which shafts 16, 17 carry lobed stirring blades 21, 22, the ends of the shafts extending beneath the feed hopper where they carry feed screws 18, 19. The stirring blades 21, 22 intermesh with some clearance and are of trochoidal cross-section so that this clearance will not vary widely as the shafts are rotated. Clearance is also provided between the stirring blades and the walls of the passageway 12. It is stated to be desirable to employ a minimum clearance of about 0.03 inches in at least one of these places. It is preferred to make the clearance between the stirring blades about 2 to 3 or more times as large as the clearance between the stirring blades and the walls of the passageway. Moreover, the clearances may vary along the length of the stirrers and this variation in clearance may be obtained altering the cross-sectional area of the passageway and/or stirrers and/or inclining the shafts 16, 17. The clearances may also vary as the shafts rotate. Additional material may be fed into the mixer through a conduit 20 and the mixed product is discharged through a conduit 23, Fig. 2 (not shown), in the end wall of the mixer. A jacket surrounding the casing and ducts through the stirrers are provided for circulation of heat-transfer medium. The stirrers may be grooved as at 29 and 31, Fig. 4, to receive overlapping baffle discs 32, 33 which form a barrier around which the materials are caused to flow.
